PLEASE STATE YOUR NAME, ADDRESS AND OCCUPATION.

My name is Bryce J. Freeman. My business address is 2515 Warren Avenue, Suite 304,

Cheyenne, WY, 82002. I am the Administrator of the Wyoming Office of Consumer

Advocate (OCA). The OCA is an independent consumer advocacy agency that was

created by an act of the legislature in the 2003 general session.

WHAT IS THE FUNCTION OF THE OCA?

Pursuant to W.S. § 37-2-401 ,

The office of consumer advocate shall represent the interests of Wyoming citizens and all classes of utility customers in matters involving public utilities. In the exercise of its powers the office of the consumer advocate shall consider all relevant factors , including, but not limited to, the provision of safe, efficient and reliable utility services at just and reasonable pnces.

ARE THE ANALYSES AND RECOMMENDATIONS OF THE OCA, IN THIS OR

ANY OTHER CASE BEFORE THE COMMISSION, INFLUENCED OR

DIRECTED BY THE COMMISSION?

No. Although the OCA is a division within the Commission according to W.S. § 37-2-

401 , it is a separate division with no reporting or supervisory links to the Commission. The

OCA has the right under W.S. § 37-2-402(ii) to appeal decisions of the Commission that it

does not find in the public interest. The only link between the OCA and the Public Service

Commission is the source of common funding provided by the assessment on gross utility

operating revenues; this assessment funds both the Commission and the OCA.

Additionally, as Administrator of the OCA, I report directly to the Governor of Wyoming.

PLEASE DESCRIBE YOUR EDUCATIONAL BACKGROUND AND

OCCUPATIONAL EXPERIENCE.

I received a Bachelor of Science degree in business administration from the University of

Wyoming in 1982. The area of concentration in my undergraduate work was statistics.

After graduating from the University of Wyoming, I was employed for three years by the

OCA Exhibit 20 I

Laramie County Treasurer as Deputy Treasurer, and then for six years by the Wyoming

Department of Revenue as a Principal Appraiser dealing primarily with utility valuation

and capital cost issues. I came to the Wyoming Public Service Commission in April of

1994, in the capacity of Senior Economist, serving in that position for approximately two

years. In 1996, I accepted a position as Lead Rate Analyst in the rates and pricing section

on the Commission Staff, and in May of2003 , I was appointed Administrator of the OCA.

In July of2004, I was appointed to a two-year term of service on the board of the Wyoming

Infrastructure Authority (WIA). In July of 2006, I was reappointed to a four year term and

in 2010, I was appointed to a second four year term on the WIA Board. In March of 2014,

after ten years of service as Secretary of the WIA Board, I rotated off of the WIA Board.

Also in 2004, I was elected to the position of Secretary of the National Association of State

Utility Consumer Advocates (NASUCA), which is a national trade association composed

primarily of state chartered consumer advocate offices throughout the country. In

November of 2010, I stepped down as NASUCA Secretary and currently serve on the

NASUCA Executive Committee. My present and past participation in both of these

organizations provides me with unique knowledge and experience upon which I can draw

in formulating advocacy positions on behalf of Wyoming utility consumers.

In 2010, I was appointed by the Board of Directors of the Western Electricity Coordinating

Council (WECC) to serve as a consumer representative on the Scenario Planning Steering

Group (SPSG). The SPSG was created to facilitate the development of a Regional

Transmission Expansion Plan (R TEP) pursuant to a contract that WECC entered into with

the U.S. Department of Energy (DOE). Funding for the RTEP project was provided by

DOE under the terms of the American Recovery and Reinvestment Act (ARRA).

Additionally, in November of 2011 , I was appointed by the WECC Board of Directors to

serve on the WECC Transmission Expansion Policy Planning Committee (TEPPC), a

WECC Board standing committee. My participation in WECC and in the RTEP project is

another source of unique and valuable insight into regional electricity issues that assist me

in advocating for the interests of Wyoming consumers.

Finally, in December of 2011 , I was elected to serve on the Advisory Council of the Center

for Public Utilities at New Mexico State University. The Center for Public Utilities (CPU)

provides training programs and current policy issues conferences to meet the needs of

professionals employed at federal and state commissions, utility companies, and other

stakeholders in the electricity, natural gas distribution, interstate pipeline,

telecommunications and water utility industries.

HA VE YOU TESTIFIED BEFORE THIS COMMISSION IN PREVIOUS

PROCEEDINGS?

Yes. I have detailed the cases in which I have testified before this Commission in Appendix

A, attached to my testimony. I have also offered testimony before the Federal

Communications Commission, the Federal Energy Regulatory Commission and the United

States Congress.

ON WHOSE BEHALF DO YOU APPEAR HERE TODAY?

I appear here today on behalf of the OCA. As I indicated previously, the OCA is an

independent party in this proceeding, separate and apart from the Commission or its

advisory staff.

AS A MEMBER OF THE OCA, DO YOU ADVOCATE THE INTERESTS OF

CERTAIN GROUPS OF CONSUMERS OVER OTHERS?

No. As a member of the OCA, it is my statutory obligation to advocate the best interest

of all citizens in the state. Specifically, W.S. § 37-2-401 states that the OCA "shall

represent the interests of Wyoming citizens and all classes of utility customers in matters

involving public utilities. [emphasis added]" This public interest standard requires the

OCA to represent the broadest possible utility consumer constituency, even though some

of those consumers may also be represented independently as parties in this case. The

OCA is responsible for balancing the positions and recommendations of the Company,

and of other parties, to arrive at a set of recommendations that serve the overall long term

public interest.

ARE YOU SPONSORING ANY EXHIBITS IN THIS PROCEEDING?

Q.

WHAT IS THE PURPOSE OF YOUR TESTIMONY IN THIS PROCEEDING?

The purpose of my testimony in this proceeding is to support the OCA's overall

recommended revenue increase in this proceeding. More particularly, my testimony will

address the appropriate rate of return to be allowed on Montana Dakota Utility Company's

(MDU or Company) invested capital, the OCA' s recommended proportion of debt and

equity capital to be included in MDU's capital structure, and the OCA's recommended

overall weighted average cost of capital (W ACC). OCA witness Mr. Anthony Ornelas will

address development of the revenue requirement in this case, and Dr. Belinda Kolb

addresses cost of service and rate design issues. In my testimony I will provide a detailed

description of the data and methods that I used to derive my recommendations in this

proceeding. I will discuss the function of capital cost in setting rates for regulated public

utilities such as MDU, general factors that influence the cost of capital required by

investors to finance utility investments and market benchmarks that provide some insight

into the range of returns currently being demanded by investors in competitive capital

markets. I will also provide a current cost of equity analysis for MDU, which I have

developed independently, that shows that the return on equity (ROE) being requested by

MDU in this proceeding is excessive and should be reduced to a level more consistent with

current capital market dynamics. I will combine my ROE recommendation with

recommendations on the appropriate cost of debt and capital structure to arrive at a

recommended overall weighted average cost of capital (W ACC). Throughout my

testimony I will reference the testimony of Company witness, Dr. J. Stephen Gaske, who

sponsors MDU' s recommended ROE, noting some areas where he and I agree and many

areas where we disagree, and the reasons therefore.

As the Commission will recall , both Dr. Gaske and I testified regarding capital cost issues

in MDU' s 2014 request to increase revenues for its Wyoming gas operations1• My review

and analysis in this case is based on the same methods and models that I have presented to

the Commission on many occasions over the last twenty years, informed by current market

information and data. My review of Dr. Gaske' s testimony suggests that he also relies on

largely the same models and methods that he has used in past proceedings before the

Commission. Consequently, the arguments in my testimony will be very familiar to the

Commission. Still, it is my intent with this testimony to clearly identify the methodological

differences between my approach and that of Dr. Gaske to capital cost estimation, and to

give the Commission a sound basis upon which to determine the appropriate cost of capital

in this proceeding.

My testimony in this proceeding is offered in conjunction with that of Mr. Ornelas and Dr.

Kolb. The analysis and recommendations of the OCA in this proceeding are offered as a

package by the OCA and are intended to provide the Commission with a basis upon which

to make a determination consistent with the public interest in this case.

AS A PRELIMINARY MATTER, WHAT RETURN IS MDU SEEKING IN THIS

PROCEEDING?

MDU is seeking a proforma overall WACC of 7.576% as shown on Statement F, page one

of one, attached to the Company's application in this matter. MDU' s proposed capital

structure consists of 42.397% long term debt, 5.502% short term debt, 1.111 % preferred

stock and 50.990% common equity. MDU requests that the Commission approve a cost

of long term debt of 5.363%, a cost of short term debt of 1.828%, a return on preferred

stock of 4.577%, and a return on common equity of 10.10%. Combining the relative

2 proportions for each of the sources of capital with MDU' s proposed cost, as described

Q.

A.

WHAT IS THE FUNCTION OF THE COST OF CAPITAL IN THE CONTEXT OF

RA TEMAKING?

For ratemaking purposes, the cost of capital is the amount of profit, or return that a

regulated utility is allowed to earn on the capital, both debt and equity, that it has invested

in the utility enterprise. The utility must acquire this capital from private investors in

competitive securities markets. Those investors have a wide variety of choices regarding

where and when to invest their dollars, ranging from mutual funds to investments in

individual stocks or bonds. Private investors are driven by a desire to maximize their

returns while minimizing their risks.

For private companies not subject to rate regulation, the amount ofreturn that can be earned

is limited only by the demand for a company' s product or service, the company's ability to

supply that demand and the ability of management to acquire capital and manage costs.

For regulated utilities, on the other hand, the judgment of the regulator supplants the

operation of the competitive market in determining what level of return is sufficient to

induce investors to provide scarce capital dollars. In either case, however, the investor

makes his decision based on the expected return relative to the perceived risk of the

investment.

From this perspective setting the appropriate authorized return for regulated utilities is

exceedingly important. If the regulator sets the rate of return too low in comparison to

investors ' perceived risk, then investors will price shares of the utility lower, increasing

the yield to a level that reflects investors' market return expectations. Under these

circumstances the utility will find it difficult to attract and maintain capital investments.

Conversely, if the return is set too high, investors will price the shares higher, reducing the

yield to a level consistent with investors' perceived risk. In this way the market is self­

correcting, but in the latter situation ratepayers would be needlessly burdened with higher

rates that are not necessary to attract and maintain capital investment. This fundamental

risk return relationship applies to every market security as shown in the classic Security

Market Line (SML):

Return

Security Market Line

Equity Risk Premium

Corporate Bond Risk

T-Bond Yield

T-Bill Yield

Stock Yield

Risk

The figure above graphically depicts the relationship between risk and return from a market

view point. Securities that have less perceived risk, such as U.S. Government debt

obligations also have a lower return and tend to cluster in the lower left of the graph. As

the perception of risk increases so does the market return demanded by investors. Moving

up the SML we find the returns for the corporate debt of large investment grade companies

and farther up still are the returns for the common equity of those same companies.

Although not shown in the figure, the returns for mid-size and smaller investment grade

companies would appear even further up the SML from large company stocks. Small cap

companies and non-investment grade securities would occupy the extreme upper right hand

comer of the graph. Theoretically, if one can accurately determine the difference between

any two of the points on the SML, often referred to as the "Risk Premium," then an estimate

of the market cost of capital can be made. The importance of this basic relationship

between risk and return will become even more apparent as I discuss the appropriate return

for MDU later in my testimony.

Q.

A.

Q.

OCA Exhibit 201

HAS THIS RELATIONSHIP BETWEEN RISK AND RETURN BEEN ADOPTED

AS A LEGAL STANDARD IN RATEMAKING PROCEEDINGS?

Yes, the critical importance of this relationship in determining an allowed rate of return

has been recognized by the U.S. Supreme Court when it established the capital attraction

and maintenance standard. This standard was established in two precedent setting cases;

Federal Power Commission v. Hope Natural Gas Co., 320 U.S. 591 (1944), and Bluefield

Water Works v. Public Service Commission, 262 U.S. 679 (1923). These cases are often

referred to collectively as the "Hope and Bluefield" standard. In Bluefield the Court found

that:

A public utility is entitled to such rates as will permit it to earn a return on the value of the property which it employs for the convenience of the public equal to that generally being made at the same time and in the same general part of the country on investments in other business undertakings which are attended by corresponding, risks and uncertainties; ....

In Hope the Court confirmed its finding in Bluefield that utility shareholders must be

adequately compensated for the risk assumed in utility investments when it found that:

..... the return to the equity owner should be commensurate with returns on investments in other enterprises having corresponding risks ....

The return should be reasonably sufficient to assure confidence in the financial soundness of the utility, and should be adequate, under efficient and economical management, to maintain and support its credit and enable it to raise the money necessary for the proper discharge of its public duties.

The Court also found, inter alia, that regulation is not a guarantee of profitability, that the

property being earned on must be devoted to public service, and that the appropriate return

to be granted depends on the facts and circumstances at the time the determination is made

and may change from time to time owing to changes "affecting opportunities for

investment, the money market, and business conditions generally".

WHY CAN'T THE COMMISSION SIMPLY SET ALLOWED UTILITY RA TES

OF RETURN AT SOME LOWER LEVEL, SAY AT A LEVEL ON PAR WITH U.S.

TREASURY RETURNS? WOULDN'T THAT BENEFIT CUSTOMERS?

A.

OCA Exhibit 201

As demonstrated by the SML above, and consistent with the tenants contained in the Hope

and Bluefield decisions, investors expect to be compensated for accepting increasing

increments of risk. Securities issued by the United States Government are risk free, at least

in theory, while utility shares are not. A utility shareholder faced with the choice of holding

a U.S. Government security or a utility share with an equivalent return would certainly

choose to hold the government security and avoid the risk of holding the utility share. This

obviously does not satisfy the capital attraction and maintenance standard set out in Hope

and Bluefield. The objective then, is to determine the equity return that is just sufficient to

induce the investor to hold the utility share rather than the government security, considering

the risk that the investor assumes when holding the utility share. This is not all together a

trivial exercise as I will demonstrate in my testimony below.

Additionally, while setting low allowed rates of return for utility companies may appear to

be in customers' best interest, setting returns that chronically fail to adequately compensate

investors for the use of their capital will have the opposite effect over time. This is due to

the fact investors will perceive that the risk of owning the utility share has increased and

adjust their return expectations accordingly, ultimately driving up the cost of financing

utility operations over future periods.

WHAT ARE THE GENERAL FACTORS THAT INFLUENCE RISK IN

FINANCIAL SECURITIES?

There are a wide variety of factors that influence risk in financial securities as perceived

by investors. Risk that cannot be diversified away by holding a large portfolio of

diversified securities is often referred to as systematic or market risk. Market risk includes

such factors as expected levels of interest rates and inflation, monetary and fiscal policies,

and the general level of economic growth and activity anticipated by investors when an

investment decision is made. To one degree or another systematic risk affects the value of

all market securities and cannot be diversified away by holding a large portfolio of

securities.

Q.

A.

OCA Exhibit 201

Non-systematic, or business risk embodies the risk of holding a particular security and

includes factors such as the characteristics of the particular market and industry in which

the company issuing the security operates, the ability of management to generate revenue

and control costs, and the ability of the company to attract capital on reasonable terms. For

regulated utilities, business risk also includes regulatory risk or the risk that the regulator

will set rates for utility services at a level that fails to produce the return expected by the

investor when the investment was made.

Investors consider all of these risk factors when making investment decisions. The essence

of risk relative to the financial markets is the probability that realized returns will be lower,

due to the risk factors cited above, than the return anticipated by the investor when the

investment was made. The higher the probability of lower realized returns the higher the

initial return demanded by the investor. Put another way, the higher the perceived risk that

actual future returns will be lower than anticipated, the lower the present value, or price, of

the security.

WHAT IS YOUR ASSESSMENT OF THE CURRENT MARKET RISKS FACING

MDU?

There are certainly risks associated with holding the debt and equity securities of private

companies in today' s market place. The general level of expected economic activity is an

important driver in the growth, or decline as the case may be, in demand for utility services.

Economic activity can be measured broadly by examining the factors that drive economic

activity such as unemployment levels, wage and compensation levels, labor productivity,

interest rates, monetary policy, and economic output as measured by Gross Domestic

Product (GDP).

As the Commission is well aware, the nation' s economy is continuing to slowly recover

from a severe recession that began in 2008 and lasted for about two years. Since the end

of the recession, national unemployment has declined from a high of 10% in 2009 to its

present level of 4.9%2. However, the labor force participation rate has remained stubbornly

low over that same period, declining from about 66% in 2008 to around 62.8% currently3•

In fact, recent small gains in job creation have been offset by an increasing labor force

resulting in unemployment remaining flat for the last several months. This increase in

labor force is driven primarily by a slight increase in unemployed or under-employed

workers returning to full time positions. Year over year growth in wages for the year

ending June 2016 was 2.5%4 while inflation increased at 2.3%5 over the twelve months

ending August 2016 which indicates essentially no growth in annual disposable income. It

should be noted, however, that most of the decline in the overall rate of inflation is due to

the declining price of crude oil over the last two plus years. Excluding the two volatile

categories of food and energy, the inflation rate was 1.1 % for the period ending August

20166. Generally, consumers are hesitant to make long term spending commitments based

on price reductions in these two volatile commodity categories. Since consumer spending

drives about 70% of economic activity in the U.S . economy, the level of unemployment

and the growth in wage compensation are important factors contributing the consumption

of goods and services measured by GDP.

Growth in GDP has similarly been lackluster since the recovery began in 2010. During the

period 2010 to 2014 the annual average rate of growth in real GDP (not adjusted for

inflation) has been 2.21 %7 which compares to a long term average growth in real GDP of

3.3%. The Congressional Budget Office (CBO) expects the growth in real GDP over the

period to 2026 to average 2.0%8, consistent with projections of the U.S . Department of

Agriculture which projects real GDP growth of 2.42%9 over the period to 2030. Both of

these projections are significantly lower than the historic rate of growth in real GDP and

both reflect recent downward revisions.

According to the U.S. Bureau of Labor Statistics (BLS), labor force productivity gains

since the end of the recession have been essentially in line with average productivity gains

realized over the period from 1987 through 2013. The BLS reports that during the period

2010 through 2015 average annual growth in productivity was 2. 7% while the average over

the period 1987 through 2013 was 2.9%. 10 By contrast, productivity gains during the last

sustained economic growth period from approximately 1995 through 2000 averaged 5%.

Productivity gains in the range of 2.5% to 3.0% are consistent with the slow economic

growth that has occurred since the end of the recession and is expected to continue over

the long term as cited above.

Although U.S. monetary and fiscal policy has firmed up incrementally in the last year it is

still highly uncertain. In December of 2015 the Federal Open Market Committee of the

Federal Reserve Bank (Fed) increased its target short term interest rate from .25% to .5%.

Various observers have speculated in recent years that the Fed would begin increasing rates

to levels more consistent with the historic range. For context, in 2008 the Fed short-term

interest rate stood at a level over 5%.

However, in succeeding quarterly meetings over the intervening year the Fed has declined

any further increases in its short-term rate target. In relaying its rate decisions to the public

the Fed has repeatedly cited labor market challenges, the lack of productivity increases,

nascent inflation and slow underlying national and global economic growth as headwinds

for the U.S . economy. Absent a rapid improvement in these metrics the Fed is likely to

pursue a course of cautious and deliberate monetary tightening over a period of the next

several years.

As the economy has continued on its slow trajectory of recovery, and the Fed has

implemented one incremental increase, it would be reasonable to expect an increase in long

WHAT DOES ALL OF THIS PORTEND FOR THE FUTURE OF THE UTILITY

INDUSTRY?

Based on the information discussed above, it certainly appears that the U.S. economy can

expect an extended period of slow economic growth. Since energy is a basic input into the

production of goods and services, the fortunes of the utility industry are tied quite closely

to the health of the overall economy and it is likely that utilities will see subdued growth

quite similar to that of the overall economy. Electric load growth, for example, is likely to

be flat or declining for an extended period of time lessening the need for utilities to finance

large capital investments in new generation and transmission infrastructure. In tum this

will lessen the construction and financing risk that utilities, including MDU, would

otherwise face if demand were increasing. The prospect for slow growth is reflected in the

projections of professional equity analysts which I will discuss in detail later in my

testimony. For example, in its July 29, 2016 summary of the electric utility industry, Value

Line found that 13:

And it's not as though the industry's growth rate is accelerating. On the contrary, load growth for many utilities is anemic.

OCA Exhibit 201

In that same edition, Value Line goes on to state that14:

Low interest rates are mostly positive for utilities. Investors are seeing what effect this has on stock prices. Utilities borrowing costs are much lower too. The downside is that, when utilities receive rate orders low interest rates mean that their allowed returns on equity are also low. Today it is not unusual to see an electric company's allowed ROE below 10%. Note, too, that earned ROEs are usually below allowed ROEs. Nevertheless, the advantages of low interest rates outweigh the disadvantages.

Investors choose to hold equity shares for a number of reasons but, a relatively important

element of an investor' s decision to invest in a particular share is the growth in dividends

and share price appreciation expected to be derived from owning the share. This is

particularly true for utility companies which typically pay out a greater proportion of their

earnings in the form of dividends than the average publicly traded company. Since a

utility ' s ability to grow dividends is directly correlated with its ability to grow earnings it

is the potential growth in earnings that is of interest to investors. Generally speaking there

are two ways to grow earnings; increase revenue or cut cost. In today' s economic

environment, with flat to declining loads and diminished need for large capital investments

it will be difficult for utilities to grow revenue. Cost containment can be an effective way

to increase earnings in the short term but there is a limit to how much costs can be cut

before service quality and reliability suffer. Prospective growth, both for privately held

companies, including utility companies, as well as the overall economy, is likely to be quite

low for the foreseeable future. Investors recognize this and have priced shares accordingly.

IS THERE EVIDENCE THAT WE CAN OBSERVE IN THE MARKET THAT

SUPPORTS THIS HYPOTHESIS?

Yes, a simple examination of market dividend yields supports this hypothesis in general

terms. The dividend yield is simply the ratio of expected dividends in the next period to

the current stock price. The current dividend yield on the dividend paying stocks included

in the S&P 500 stock index is currently 2.07% 15 while the yield on the Dow Jones Utilities

2 Index is 3.4%. 16 This strongly suggests that utility equity investors understand that

3 prospects for growth in the utility industry are limited in comparison to the broader market,

4 thus they demand more of their return upfront in the form of dividend yield in order to

5 balance the value of utility shares against the value of alternative equity investment

6 opportunities that may have lower expected dividends but higher potential for growth. It

7 should be noted, however, that the dividend yield for a sample of comparable utility shares

8 tracked by the Value Line Investment Survey was 5 .19% at the time of MDU' s 2009

9 electric rate case17. So, even though utility dividend yields are much higher than those of

1 o the broader market, they have in fact declined, consistent with declining yields in the

11 broader market, indicating a general decrease in investors' perceived risk.

Q. WHAT ARE THE RISKS PECULIAR TO THE ELECTRIC UTILITY INDUSTRY

OR MDU ITSELF THAT ARE NOT REFLECTED IN THE RISK FACTORS

THAT YOU HA VE ALREADY DISCUSSED?

16 A. In addition to the market risk factors discussed above, MDU is also subject to certain

discrete risk factors that do not factor into overall market risk. As I discussed earlier in my

testimony, business risk is attributable to such factors as the particular industry and market

in which a company operates, the ability of the company and its management to grow

earnings, and the degree to which the company' s financial policies either enhance or

degrade its prospects to grow earnings in the future.

states. Rocky Mountain Power, for instance, which operates in many states, is able to

diversify the risk of a cyclical economic downturn in any particular service area in which

it operates since it is likely that some or all of its other service areas would experience a

contemporaneous counter-cyclical upturn. In both cases, however, utility shareholders

would benefit from the fact that MDU and Rocky Mountain Power are both afforded the

protection of the regulatory compact that does not inure to non-regulated companies.

Similarly, from a business risk perspective, MDU benefits from its association with MDU

Resources, a very large and diversified holding company. Being a part of the MDU

Resources corporate family in effect allows MDU Utilities to diversify away a large part

of the shareholder risk that would otherwise be present if MDU Utilities were a stand-alone

company.

IS THERE ANYTHING ABOUT MDU'S SHERIDAN AREA SERVICE

TERRITORY THAT WOULD MERIT AN INCREASED RISK PREMIUM?

No. In spite of the statewide downturn in the energy complex, of which we are all well

aware, MDU's Sheridan service area seems to be remarkably resilient and stable. Sheridan

County's mineral tax valuation has dropped by approximately 90% since 2009 after

reaching a high of about $400 million. State and local property taxes, on the other hand,

have exhibited modest growth over that same period 18 . Sheridan County's median

household income has been trending up incrementally and is slightly lower than the median

for Wyoming but slightly more than the median U.S. household income 19• The poverty

rate in Sheridan County has also been trending lower2°. The county's school enrollment is

up by about 8% over the last five years21, while the county's overall population has grown

by almost 11 % over the last decade22, slightly slower than the state overall. Sheridan

County' s work force has remained fairly stable at around 15,000 employed residents23 and

unemployment in the county stood at 4.1% at the end of July 2016, approximately 100

basis points lower than the Wyoming and U.S. unemployment rates24. The county has also

experienced modest but positive wage gains over the last several years25.

Based on this data, I conclude that there is no reason to ascribe any special risk premium

to the cost of financing MDU's Sheridan County electric utility operations. Rather, I

believe MDU's Wyoming service territory is stable and is characterized by modest but

predictable growth. The cyclical downturn in the energy market, while it has obviously

negatively impacted the operations of other utilities in Wyoming, does not appear to have

had a material impact on MDU's Wyoming operations. As such, I believe it is reasonable

to use a sample set of comparable companies to infer equity financing costs for MDU

without making any special risk premium provisions. I will discuss the concept of

comparability later in my testimony.

DO YOU AGREE WITH DR. GASKE'S ASSERTION THAT THE SMALL SIZE

OF MDU'S WYOMING UTILITY OPERA TIO NS WARRANT A LARGE RISK

PREMIUM IN COMPARISON TO OTHER UTILITIES?

Absolutely not. Dr. Gaske argues that based on Ibbotson Associates data, unregulated

firms that are similar in size to MDU's Wyoming electric operations enjoy a size premium

of 1,430 basis points over the average return on long term corporate bonds and that his

recommended ROE is low in comparison.26 Dr. Gaske further argues that a size premium

adjustment of at least 100 basis points over the return required by the typical [electric]

proxy company is warranted, although he provides no basis upon which to conclude that a

What Dr. Gaske fails to recognize is that MDU is not a small cap company comparable to

those referenced in the Ibbotson publication. Investors cannot purchase a share of equity

in MDU Resources that represents only the Wyoming electric utility operations. Rather,

when investors purchase an equity share of MDU Resources they are purchasing the right

to receive dividends derived from the earnings of all of MDU Resource's operations. MDU

Resources is a large diversified holding company with a market capitalization of

approximately $4.6 billion which Value Line classifies as a "mid cap" company.

If Dr. Gaske wishes to estimate the required return for only the Wyoming electric

operations of MDU Resources there are other, more accurate ways to do so. For example,

Dr. Gaske could have performed what is commonly called a divisional cost of capital

analysis. Dr. Roger Morin devotes an entire chapter in his book "New Regulatory Finance"

to the topic of "Divisional Cost of Capital and CAPM Applications".28 As discussed by

Dr. Morin there are many techniques that can be used to estimate the required return on

discrete assets or operations oflarger companies. Most of these techniques revolve around

attempting to measure the difference in risk, primarily on a subjective basis, between the

assets or operations held as part of a larger corporate family and the estimated risk if they

are assumed to be held and operated as a stand-alone enterprise. The most common

measure of risk in a divisional cost of capital analysis is beta which is a statistical measure

of the price volatility of equity shares in comparison to the overall market. I will describe

the application of beta as a measure of risk in more detail later in my testimony. But for

now, this brief description provides a convenient segue into my next point regarding Dr.

Gaske's flawed logic on the subject of size premia.

OCA Exhibit 201

As correctly pointed out by Dr. Gaske, nearly all of the companies tracked by Ibbotson in

its size premia deciles are unregulated companies and not comparable to utility companies

generally or MDU utilities specifically. This is obvious when one observes the average

betas associated with each of the deciles taken from the Ibbotson Associates 2016 SBBI

Yearbook29. For example, Ibbotson calculates the average beta for companies included in

the smallest sized market capitalization decile, where MDU' s utility operations would fall

if viewed on a stand-alone basis, to be 1.39. The resulting size premium for companies in

this decile, as recommended by Ibbotson, is 5.60%, or 560 basis points, not the 1,430 basis

points suggested by Dr. Gaske.

We can see from the average beta, however, that even this size premium adjustment is

inconsistent with any measure of comparable risk. Companies comprising this decile are

the smallest of the small, almost entirely unregulated companies, and as such exhibit betas

that are wholly incomparable to that of regulated utilities. For instance, the average beta

for the electric and combination electric and gas distribution companies followed by Value

Line is 0.72. The market is assumed to have a beta of 1.0 implying that the Value Line

electric and combination utilities are, on average 28% less risky than the market. With a

beta of 1.40, Dr. Gaske would have us believe that MDU' s Wyoming gas operations are

40% more risky than the market overall, simply due to its small size. By contrast, my

proxy group of comparable companies, the derivation of which I will describe later in my

testimony, have an average beta of 0.74. These are highly regulated companies that derive

a majority of their revenue from electric and natural gas utility operations and are far more

comparable than the unregulated companies contained in the smallest market cap size

decile published by Ibbotson.

To put an even finer point on this argument, the companies that comprise the top decile of

capitalization, the largest of the large, have an average beta of 0.91 , considerably higher

than the average for the Value Line gas and electric companies. Ibbotson suggests that the

size premium for these companies should actually be negative at -0.36% meaning that the

market risk premium should be adjusted downward for companies of this size and risk.

Assuming an average beta more consistent with that of the regulated utilities followed by

Value Line would suggest that the size premium advocated by Dr. Gaske should, in fact,

be negative.

Based on the forgoing discussion, it is my opinion that attempting to make a size premium

adjustment based on published size premium data for regulated utilities in general, and

specifically for MDU in this proceeding, is inappropriate and will lead to a gross

overstatement of the required market equity return for MDU in this case. Importantly, one

of the methods for properly assessing the required return on equity for an operating division

of a larger diversified company, as discussed by Dr. Morin in his book, is the "Pure Play"

method. In this method the analyst seeks to estimate ROE using financial and market data

from proxy companies that are as nearly comparable as possible to the subject operating

division. As I will describe later in my testimony that is essentially the method that I have

used to arrive at my recommended ROE in this proceeding.

HOW SHOULD INVESTMENT RISK BE ACCOUNTED FOR IN A COST OF

EQUITY ANALYSIS?

In the development of my recommendations on cost of capital I assess the risk faced by the

utility in the same manor that investors assess risk, on a relative basis. It is a relatively

simple matter to identify individual factors that might influence the risk faced by a subject

utility. The question then becomes; are those risks extraordinary or in addition to the risks

being faced by similarly situated companies. Going back to the tenants of the Hope and

Bluefield decisions, a utility return should be comparable to those of similar companies

attended by similar risk. As I indicated earlier in my testimony, I can find no rational basis

upon which to attribute greater risk to MDU than the companies in my proxy group and

therefore recommend an ROE that is consistent with the expected returns for my proxy

group.

COMPARABLE COMPANIES

Q.

A.

IN LIGHT OF THE FOREGOING DISCUSSION OF RISK, HOW DID YOU

BEGIN YOUR ANALYSIS OF THE APPROPRIATE ROE FOR MDU?

I began my analysis in this proceeding, as I customarily do, by gathering data from the

Value Line Investment Survey (Value Line) on the forty three companies classified by

Value Line as electric utilities or combination electric and natural gas utility companies.

Unlike Dr. Gaske who included only electric companies in his proxy, I included

combination electric and natural gas utilities in my proxy group since MDU is a

combination electric and natural gas utility. Excluding combination utilities which are

comparable in practice to MDU would unnecessarily limit the sample size of comparable

companies (Value Line lists only 17 natural gas distribution companies) increasing the

probability that the data will not be random and truly representative of MDU.

The object of this exercise is to gather publicly available financial information for

companies that are as comparable to MDU as possible so that information can be used to

generate a cost of equity estimate. As outlined in the Hope and Bluefield cases discussed

earlier, MDU is entitled to a return on its investment in plant and facilities devoted to public

utility service that is commensurate with returns being earned by comparable companies

with similar risk. The sample group of companies, after incomparable companies are

eliminated, will become the basis of the comparative analysis required under Hope and

Bluefield.

From Value Line I gathered such information as capital structure, growth in earnings,

dividends and book value, estimated dividends, estimated return on equity and estimated

earnings per share. I supplemented the Value Line information with information on bond

ratings and the relative percentage of regulated revenues for the companies in Value Line.

I obtained share price information from the Wall Street Journal Online Edition and, in

addition to Value Line, I took analyst's earnings growth forecasts from Yahoo Finance and

Zacks Investment Research both of which are available online.

After gathering this data on the forty-one companies followed by Value Line I screened

the companies to assure comparability with MDU. First, I eliminated companies for which

I could not obtain complete and useful financial information from Value Line.

2 Additionally, since MDU Resource' s (MDU's parent company) bond rating is BBB+ from

3 S&P (MDU is not rated by Moody's Investor Service), I restricted the companies in my

4 sample group to those with a bond rating of at least BBB from S&P. I also eliminated

s companies with unstable financial histories and for which dividends and earnings are not

6 expected to grow in the future. I also required each of the proxy companies to derive at

7 least 70% of their total revenue from regulated utility operations; many of the combination

8 electric and gas companies in my sample derive more than 70% of their operating revenue

9 from electric operations.

10 Finally, I also eliminated companies that are currently engaged in merger or acquisition

11 activities. Such activity tends to skew the price that investors are willing to pay for a share

12 of the utility based on anticipated gains or losses resulting from the merger or acquisition

13 rendering any comparison made against that company unreliable. The resulting set of

14 fifteen companies shown in OCA Exhibit 202.1 are highly comparable to MDU. Dr.

15 Gaske 's ROE estimate relies on eleven proxy companies, only three of which are included

WHAT WAS THE NEXT STEP IN YOUR ANALYSIS?

Following my selection of a suitable group of sample companies I calculated various

indicators of the cost of equity capital for each, including the basic Constant Growth

Discounted Cash Flow (DCF) model, three versions of the multi-stage DCF (NCDCF)

model, and a Capital Asset Pricing Model (CAPM) indicator. I also calculated a quarterly

compounding version of the DCF model. However, my quarterly DCF model is

substantially different than that of Dr. Gaske. I will describe the theoretical underpinnings,

data requirements, assumptions used and results of each of these indicators in my testimony

below.

PLEASE DESCRIBE THE CONSTANT GROWTH DCF MODEL AND ITS

RESULTS.

Certainly. The premise of the DCF model is that investors make their decision to invest in

the equity shares of a company based on the present value of the future cash flows expected

to be derived from the investment. Reducing the future cash flows to a present value

enables investors to easily compare available investment opportunities. Notationally, the

classic DCF formulation is expressed as follows:

On Dn(1-g)

Po= + + x 1+K (1 +K)2 K-g

9

Where: K = Cost of Equity

Di = Dividend in Period 1

Po = Current Stock Price

g = expected growth in dividends

The DCF model noted above can be simplified and expressed in the form traditionally used

by investors to ascribe a price to a share of stock which embodies all of the future cash

flows that the owner expects to receive as a result of the ownership of that share. The

traditional share valuation model is expressed as follows :

n

Pa=L t= l

01 +g (1 +K)t

Where: All variables are as previously listed

As can be seen from this derivation, the investor is interested in ascertaining the price that

should be paid for a share given that the investor already knows what rate he or she will

use to discount the future revenue stream and what growth rate can be expected in the form

of growth in dividends and share price appreciation. The regulator, however, is interested

in determining the implicit discount rate and rate of growth given the observable price that

the investor is willing to pay. This valuation model can be manipulated algebraically to

solve for the discount rate K and expressed as follows :

This expression is the standard form of the constant growth DCF model. It is appealing

and deceptively simple because it relies on readily available market observations for the

current price and expected dividends to derive the current dividend yield (D J!Po in the

above equation). The difficulty arises in assigning a value to growth, g. Growth is the rate

at which investors expect future dividends and share price to grow over an infinite holding

period. While some argue that price, Po, should be averaged over some historical period

from a few days to a few months, and others argue that dividends, D 1, should be estimated

on a quarterly rather than annual basis, it is the estimation of g that typically generates the

most controversy in regulatory proceedings.

For his part, Dr. Gaske uses a six month historic average of the share prices for the

companies in his comparable group in calculating the dividend yield for each of his proxy

companies. I continue to believe that using a share price as near to the rate effective date

as possible is a much better reflection of investors' perceived risk than an average of prices

over some arbitrary historical period. Investors' decisions are based on current

expectations about future returns and the current price efficiently and effectively

incorporates those expectations; historical prices, even over a short period, may be

significantly disconnected from investors' expectations about the future, particularly in

periods characterized by market volatility. Therefore, I have used the closing spot price as

of September 1, 2016 to represent the price component of the dividend yield in the constant

growth DCF model set out above, as shown in Column M of OCA Exhibit 201.1. For the

expected dividend component of the current dividend yield I use Value Line's projected

2017 dividend. This is consistent with the construct of the annual constant growth DCF

model which calls for expected dividends in the next period (year). The calculated

dividend yield for each company is shown in Column N of that same exhibit.

As shown in Column 0 of that exhibit, I also made an adjustment to the dividend yield of

each company to reflect the costs associated with issuing equity. Similar to the issuance

of utility debt securities there is a cost associated with issuing equity, for example, legal,

underwriting and marketing expenses. For debt instruments these fees are customarily

included in the cost of debt and amortized over the life of the security. For equity however,

there is no obligatory schedule of dividend payments and therefore it is necessary to adjust

the dividend yield in order to properly reflect the fact that expenses are incurred in the

issuance of equity. Ignoring those costs deprives the utility of earning a full return on its

outstanding equity, if only by a very small amount.

In developing my floatation cost adjustment I relied on the data provided in Dr. Gaske's

Exhibit JSG 2, Schedule 2, which is a computation of the actual floatation costs associated

with equity issuances by electric companies over the period 2005 to 2015. The

approximate average of the floatation costs, 3.3%, associated with these issuances is

reasonably consistent with floatation costs estimates that I have seen in the past and I have

no reason to question their validity. I do object, however, to the way in which Dr. Gaske

incorporates his floatation cost estimate into his DCF analysis.

Dr. Gaske mistakenly multiplies the end result of his basic DCF calculation by 1.03330 to

account for floatation costs, effectively increasing his estimated ROE by as much as 50

basis points. The appropriate method to account for floatation costs, on the other hand, is

to adjust the dividend yield in the DCF model to account for floatation costs as follows: 31

r=D1/P(l-f) + g

The difference between the standard DCF model and the floatation adjusted model is that

the dividend yield, D1 /P, is divided by 1- f (floatation cost estimate). This is because the

cost of issuing equity reduces investors' yield but does not impact the future growth

expected by those same investors. The treatment of growth between the two models is

identical. The example in the table below shows the magnitude of Dr. Gaske's mistake,

assuming a dividend yield of 3%, floatation costs of 4% and growth of 5%:

My flotation cost adjustment effectively adjusts the estimated cost of equity upward by

increasing the dividend yield by an average of approximately 15 basis points. Dr. Gaske's

erroneous adjustment increases the indicated cost of capital produced by the standard DCF

model by about 30 basis points.

WHAT ESTIMATE OF GROWTH HAVE YOU USED IN CALCULATING THE

CONSTANT GROWTH DCF MODEL?

There are several methods that an equity analyst can use to estimate the growth component

required in the constant growth DCF model. I'll begin with earnings growth estimates

provided by professional equity market analysts. Professional equity market analysts

follow the shares of many publicly traded companies. By analyzing the underlying

performance of the issuing company, equity analysts project future performance according

to such metrics as revenues, returns, earnings and dividends per share, price earnings ratio,

and others. These analysts routinely publish their projections in the trade press and those

projections are widely relied upon by investors when formulating their investment

decisions. They are also a widely used source of information for Commissions in making

return determinations in cases such as the instant case.

I have used three separate sources of analysts' growth estimates in my constant growth

DCF model; Value Line, Yahoo Finance and Zacks Investment Research. The five year

earnings growth estimate, which is the longest projection made by analysts, is shown in

Columns P, S and T of OCA Exhibit 201.1. I rely exclusively on earnings growth estimates

in my analysis because earnings provide the cash with which dividends are paid and

because Value Line is the only estimating service that provides dividend growth estimates;

Yahoo and Zacks provide only earnings growth estimates. In theory, assuming a constant

dividend payout ratio, earnings and dividends would grow at the same rate in any event. I

should note that Dr. Gaske uses analysts ' estimates from Yahoo and Zacks and does not

consider the earnings growth estimates provided by Value Line.

I weighted the growth estimates from each reporting source equally in my calculation of

the constant annual growth DCF model. The results of my constant growth DCF indicator

using analysts' projections of growth, and adjusting for floatation costs, are shown in

Column AF of OCA Exhibit 201 .1. The median constant growth DCF indicator for the

proxy group is 9.22%

DID YOU CONSIDER OTHER METHODS OF ESTIMATING GROWTH IN

YOUR ANALYSIS AS WELL?

Yes, I also incorporated a long term projection of GDP growth based on both historic and

estimated growth in GDP into the various versions of my constant growth DCF model. In

addition, I also included an estimate of sustainable growth in one version of my constant

growth DCF model. I will describe all of these indicators more fully below.

Incorporating growth in long term GDP as a proxy for growth in the DCF model is based

on the premise that over the very long term a company's earnings growth cannot be

sustained at a level higher than that of the overall economy. During shorter periods

earnings may grow faster or slower than GDP but over the long term earnings will revert

to the mean level of growth for the economy as a whole. From a theoretical perspective

the theory is sound. But, in practice it has precisely the same short-coming as that of other

methods of projecting growth; specifically, estimating the rate of future GDP growth.

Historic GDP growth is well documented and widely available in the public domain. For

example, the Federal Reserve Bank of St. Louis provides information on both nominal and

real GDP growth from 1947 to the present.32 During this period GDP growth averaged

6.4%, ranging from a high of 13% in 1978 to a low of -2% in 2007. Between 1990 and

2007 nominal GDP growth ranged generally between approximately 4% and 6%. The

As I have done in past cases in which I have testified before the Commission, I have relied

upon the historic nominal GDP growth rate data provided by the Federal reserve bank of

St. Louis for the period 1953 to present, weighted to more recent years, in formulating my

estimate of future GDP growth based on actual historic GDP growth.

In my analysis I have weighted each observation according to its chronological place in the

data set. For instance, the observation for 1953 gets only one sixty second of the weight

of the observation for 2015 in my analysis. My method considers all observations in the

data set but gives proportionally more weight to more recent GDP growth rates. My

analysis results in an estimated GDP growth rate of 3 .1 % based on weighted historic

nominal growth in GDP over the period 1953 to 2015. Incorporating this estimate of

growth into my constant growth DCF model results in a median estimated cost of equity

of 6.40% for my sample group of companies as shown in Column AG of OCA Exhibit

201.1.

OCA Exhibit 201

DO YOU BELIEVE THAT THIS A REASONABLE ESTIMATION OF LONG

TERM GDP GROWTH IN THE FUTURE?

None of us knows with any degree of certainty how GDP will grow in the future,

particularly over the type of infinite time horizon assumed in the DCF model. Therefore,

we are required to make some assumptions and judgments to arrive at a growth rate that

reasonably represents a plausible future growth rate. After all, we are trying to measure

investors ' expectations about the future since the exercise of measuring capital cost is

meant to support the capital attraction and maintenance standard established in the Hope

and Bluefield cases. It is not unreasonable to assume that future growth, both for individual

companies and the economy in general, will follow the same broad patterns that it has in

the past. From that perspective, my estimate of GDP growth based on historic observation

is plausible, but there are certainly other estimates of future GDP growth that may be a

more accurate representation of investors' future expectations for growth. In weighing this

particular indicator I give it no weight in my final estimation of ROE for MDU.

WHAT OTHER ESTIMATES OF GDP GROWTH HAVE YOU CONSIDERED IN

YOURDCF ANALYSIS?

Although there are many sources of GDP growth estimates, some public and some private,

I have used the estimates provided by the Congressional Budget Office (CBO) in its

publication: The Budget and Economic Outlook: 2015 to 2025. The CBO is a non-partisan

organization that provides budget, monetary, economic and policy analysis to the U.S.

Congress. Its analysis and estimates are widely relied on by Congress, Federal Agencies

and the private sector in formulating spending and investment decisions. The CBO' s

analytical methods are as credible as any other available source. The CBO estimates that

U.S. GDP will grow at an annual average rate of 4.0% over the period 2014 through 2026

with real GDP growth averaging 2.0%. This implies an annual average rate of inflation of

2%.

OCA Exhibit 20 I

I also looked at GDP growth estimates developed the USDA as referenced earlier in my

testimony. 33 In its analysis the USDA estimates that real GDP will grow at an average rate

of approximately 2.42% over the period to 2030. The USDA' s analysis is based on

information from the World Bank, the International Monetary Fund, IHS Global Insights

and Oxford Economics, among others. If inflation continues to average 2% over that same

period then nominal GDP growth will average about 4.6% to 2024, consistent with the

estimates provided in the CBO publication discussed above. Although both the CBO and

USDA expect GDP growth to increase slightly this year, both organizations expect GDP

growth to resume a lower stable pattern of growth in the later years of the forecast period.

Incorporating the CBO's estimate of annual average nominal GDP growth into my constant

growth DCF model results in a median estimated cost of equity of 7.30% as shown in

Column AH of OCA Exhibit BJF 201.1.

IS THE CBO ESTIMATE OF FUTURE GDP GROWTH CREDIBLE AND

REASONABLE IN YOUR OPINION?

Absolutely. As I indicated earlier, the CBO's economic and budget projections are widely

used and relied upon by both government and private entities. Some market analysts argue

that some government forecasts for lower GDP growth are biased downward since they are

based on an assumption of permanently low inflation of around 2%. In fact, Dr. Gaske

suggests that inflation wi 11 increase in the future and by extension long term interest rates

will rise as well. 34 However, a 2% annual inflation rate is widely recognized as the inflation

rate that the Federal Reserve Bank's Federal Open Market Committee (FOMC) is targeting

with its monetary policy tools. It is also identical to the inflation rate of 2.0% implicitly

incorporated into the CBO's GDP growth projections.

As further support for the efficacy of a long term inflation rate in the range of 2% we need

only observe in the market what actual investors expect inflation to be over the long term.

OCA Exhibit 201

The U.S. Treasury issues 30 year Treasury Bonds which are currently yielding about 2.4%

(as of October 6, 2016). It also issues 30 year Treasury Inflation Protected Securities

(TIPS) which are currently yielding 0.67%. Purchasers of 30 year Treasury Bonds, if held

to maturity, will earn the coupon rate on the face of the bond. Purchasers of TIPS earn a

return that is indexed to the rate of inflation. The difference between the yield on a 30 year

bond and a TIPS is the implicit rate of inflation expected by real investors investing real

dollars in Treasury securities. The current difference, 1.77% (2.435% - 0.671% = 1.764%),

representing investors ' expected inflation rate, is even lower than the inflation rate assumed

by the CBO in its long term GDP projections and the Federal Reserve Bank's target

inflation rate. In my view, the GDP growth projections made by the CBO are both

reasonable and credible and if anything may tum out to be high given the outlook for

inflation.

DID YOU CONSIDER ANY OTHER GROWTH PROJECTIONS IN YOUR

CONSTANT GROWTH DCF ANALYSIS?

Yes, I also looked at a projected rate of growth based on the sustainable growth rate

approach similar to that provided by Dr. Gaske. Sustainable growth is based on the premise

that future growth in dividends (which are derived from earnings) can only occur if a

portion of the earnings that would otherwise be paid out in dividends is reinvested in the

company.35 The level of sustainable growth (aka the retention ratio growth method) is

expressed as:

g = bxr

where "b" is the fraction of earnings retained and "r" is the expected return on the book

value of equity. Value Line publishes expected earnings and dividends per share from

which a retention ratio (b in the above equation) can be derived, as well as the expected

return on equity. These calculations are shown in Columns U through Y of Exhibit OCA

201.1. The resulting median sustainable growth rate of 4.20% is shown at the bottom of

Column Y of that exhibit. Combining the sustainable growth rate with the floatation

adjusted dividend yield for each company in my sample group produces an estimate of the

cost of equity for MDU of 7 .68% as shown in Column AE of OCA Exhibit 201.1 .

IS THIS A RELIABLE METHOD OF PROJECTING GROWTH?

It can be. But, just like all other methods and sources, it has its short comings. The

information that I have used from Value Line to calculate sustainable growth is projected

information. There is always an element of uncertainty associated with projections.

Additionally, the Value Line projections are the work of a single analyst rather than a

consensus of many analysts, making those projections less reliable than, for example, the

multiple analysts ' opinions I include in the analysts' growth rate forecast that I described

earlier. Finally, analysts are predicting earnings growth in the range of 5.4% and the CBO

is predicting GDP growth in the range of 4.0%. At 4.2% the sustainable growth rate is in

the range of both analysts' and government forecasts for growth. I should also note that

Dr. Gaske recommends a much lower retention growth rate, approximately 3.65%36, than

I do. However, Dr. Gaske then blends this lower growth rate with higher analyst growth

rates to arrive at a blended growth rate in excess of 5%37

Since Dr. Gaske and I both use the same methodology and Value Line source data to

compute our respective sustainable growth rate estimates, it appears that the difference in

the two estimates is related primarily to the proxy groups that we are using. Dr. Gaske

limits his proxy group of comparable companies to electric utility companies and

consequently his sample group is smaller than mine. For the reasons discussed earlier in

my testimony I also include combination electric and gas utilities in my proxy group. There

also may be some minor differences in our sustainable growth estimates due to the fact that

DID YOU ALSO CONDUCT DCF ANALYSES BASED ON THE PREMISE THAT

GROWTH IS NOT CONSTANT INTO PERPETUITY?

Yes. I computed three versions of the non-constant growth DCF model incorporating

different combinations of the various growth rates discussed previously. The non-constant

growth DCF (NCDCF) model is predicated on the assumption that dividends will grow at

some constant rate in the near term and a constant but different rate thereafter. For this

analysis I have assumed that analysts ' growth rate projections are the most reliable

estimation of growth over the next five years and that after the initial five year period,

growth will revert to the long term mean growth rate of GDP, either based on historical

observations or based on the estimates provided by the CBO as discussed earlier. I also

developed an NCDCF estimate based on my sustainable growth estimate.

Essentially, my NCDCF model is an Internal Rate of Return (IRR) calculation that projects

the cash flows associated with owning a share of the equity of each of the companies in my

certainly longer than the useful life of utility assets or the investment time horizon of the

negative cash flow. The results of my NCDCF calculations are shown in Exhibits OCA

BJF 201.2, 201.3 and 201.4. Each of these exhibits begins with the five year analyst growth

forecast described earlier and substitutes the CBO estimated GDP growth rate, the long

term historic GDP growth rate, and the sustainable growth rate, respectively, for the second

stage or long term growth rate. As shown on the exhibits, the results of my NCDCF

analyses range from 7.0% to 7.84%.

DID YOU ALSO CONDUCT A QUARTERLY DCF ANALYSIS?

Yes, as I mentioned earlier in my testimony, I also conducted a quarterly DCF analysis.

The quarterly DCF model is a slightly modified version of the basic constant growth DCF

model discussed extensively above. In the quarterly DCF model the fact that public

companies typically pay dividends on a quarterly basis is accounted for in calculating the

dividend yield. Therefore, the quarterly DCF model takes the form38:

K=

[d1(l +K)';. + d2(1 +Kf 2 + d3(1 +K) ';. + d4]

Po

Where: K = Cost of Equity

d = Dividends in Quarters 1 -4

Po = Current Share Price

g = Growth

+ g

The essence of the quarterly compounding DCF model is that since dividends are paid on

a quarterly basis they are available to be reinvested, also on a quarterly basis, thus

compounding their value to the shareholder. This concept is not unlike what is experienced

when on places money in an interest bearing account that pays compound interest. For

example, most pass-book savings accounts pay interest on the amount in the account at the

end of the period, including any interest payments paid in previous periods. In this way

the account pays interest not only on the original principal sum invested (simple interest)

but on the accumulated interest as well (compound interest). The quarterly compounding

DCF model is based on exactly the same premise.

The quarterly DCF model is solved iteratively, which is made much easier using a

computer spreadsheet application. Essentially, one substitutes values for K on the right

side of the equation until those values exactly equal Kon the left hand side of the equation.

In OCA Exhibit BJF 202.5, Columns AI through AL, I show the results of my quarterly

DCF analysis, again showing results based on the four different growth estimates discussed

earlier in my testimony. I should also note that I have again adjusted the yield in my

quarterly DCF model to reflect floatation costs. The results of my quarterly DCF analysis

range from 6.35% to 8.51 %.

DO YOU HAVE ANY OBSERVATIONS REGARDING DR. GASKE'S

QUARTERLY DCF ANALYSIS?

My understanding of Dr. Gaske ' s quarterly DCF analysis is that it is actually not a quarterly

compounding DCF model at all. Rather, Dr. Gaske assumes that the next dividend to be

received by investors will be received between one and three months hence and simply

assumes that his estimate of growth will apply to dividends paid after that time. In effect,

Dr. Gaske is merely adjusting the dividend to reflect an arbitrary point during the next

period (year) when dividends will grow. This in no way accounts for the compounding

effect that would occur if one assumes that dividends are reinvested on a quarterly basis.

To be sure, if dividends are expected to grow during the period (year) then the growth in

dividends should be accounted for as well. But, that is an entirely separate matter from the

compounding that results from quarterly dividend reinvestment. In my analysis I have used

projected dividends for 2017, hence no adjustment is necessary. As a practical matter,

privately held companies, including those in my proxy group, typically make dividend

distribution decisions on an annual basis (usually in the first quarter of the calendar year),

even though those dividends are generally paid on a quarterly basis. And, again, the growth

in the projected dividend has nothing to do with the compounding that results from

quarterly dividend reinvestment.

CAPITAL ASSET PRICING MODEL

Q.

A.

WHAT OTHER INDICATORS OF THE COST OF EQUITY CAPITAL HAVE

YOU COMPUTED IN YOUR ANALYSIS IN THIS CASE?

I have also calculated a Capital Asset Pricing Model (CAPM) indicator of the cost of equity

capital for MDU. The CAPM is a discrete version of the more general risk premium model.

As I discussed earlier in my testimony, the premise of the security market line is that

investors are willing to assume additional increments of risk only in return for the

opportunity to earn additional returns. The risk premium is the quantity of additional return

demanded by investors in return for the additional risk assumption. Using this relationship

an estimate of the cost of equity capital can be made using the following equation:

Where: K =Cost of Equity RF= Risk Free Rate RM= Market Risk Premium r., =Beta

In theory, if the risk premium for a specific security can be estimated, in comparison to an

alternative security, that risk premium can be combined with the present return for the

comparative security to derive an estimate of the market cost of capital. In practice, historic

risk premiums are compiled and published by a number of private and public sources. In

my analysis I relied on data compiled by Ibbotson Associates (Ibbotson) over the period

1926 to present. Previously, the "Ibbotson SBBI Yearbook; Stocks, Bonds, Bills and

Inflation" published by Morningstar ceased publication. It is now back in print and is being

published by Duff & Phelps, a widely recognized source of financial and market

information. Dr. Roger Ibbotson is the author of the 2016 edition of the Ibbotson SBBI

Yearbook.

Ibbotson provides historic risk premiums that measure the differential return between the

stock market and long term government and corporate bonds over the period 1926 to 2015

(other periods are provided but not used in my analysis). According to Ibbotson, the

incremental return or risk premium of stocks over long term government bonds demanded

by investors over that 89 year period averaged 6.0%.39 Thus one measure of the current

cost of capital, based on the current return of long term government bonds of 2. 79% would

be 8.79% (2.79% + 6.00% = 8.79%) for the average equity share.

The above calculation, however, is only a generalized estimation of the cost of equity

capital. It is widely recognized that shares of stock are characterized by substantially

different levels of risk. In order for the risk premium to be useful for our purposes we need

a way to more definitively measure the risk associated with the shares of utility companies,

and even more specifically, the risk associated with the shares of the companies in my

sample group.

The CAPM measures this share specific risk by measuring the share price volatility of the

subject shares in comparison to the overall market. In theory, shares that are affected with

less risk will exhibit lower share price volatility over time than riskier shares and shares

with higher risk will exhibit relatively more price volatility. This share price volatility

measure is known as beta and is denoted by /!, in the above equation. The overall market

is assumed to have a beta of 1. Beta is a measure of the covariance of individual shares

with the overall market. For example, shares with a beta of 1 would have prices that vary

precisely in tandem with the market and thus in theory would have the same level of risk

as a widely diversified portfolio of stocks. Shares with a beta greater than one exhibit share

price volatility greater than that of the market in general and are said to be riskier than the

overall market. Conversely, share price volatility less than 1 indicates that a particular

share possesses less risk than the overall market.

Incorporating beta, which I have taken from the data published in Value Line, into the

above equation, we see that utility stocks have demonstrably lower risk than the overall

market; the median beta for the companies in my sample group is 0. 70 or 30% less than

the overall market. The median beta for the companies contained in Dr. Gaske's proxy

group is 0.75 or 25% less than the overall market. Combining beta with the currant risk

free rate of 2.279% and the market expected equity risk premium of 6.0%, pursuant to the

above equation, yields an estimate of the cost of equity for each of the companies in my

sample group. As shown in Column AK of OCA Exhibit 201 .1, the resulting median cost

of equity capital is 7 .18%.

DO YOU HA VE ANY OBSERVATIONS REGARDING DR. GASKE'S RISK

PREMIUM ANALYSIS?

Yes. As I explained earlier in my testimony, Dr. Gaske ' s risk premium analysis, wherein

he compares the historic returns of small company stocks to the historic returns on

corporate bonds is meaningless in the context of setting rates in this proceeding. Dr. Gaske

does not present this risk premium analysis as an indicator of the cost of equity for MDU,

but rather as a benchmark, presumably to underscore the reasonableness of his final

recommended ROE.

In his risk premium analysis Dr. Gaske erroneously concludes that the small company

stocks followed by Ibbotson's are a good proxy for MDU. As I demonstrated earlier, those

small company stocks are not even slightly comparable to MDU and any incremental size

premium derived therefrom is highly inappropriate. Dr. Gaske' s two additional risk

premium benchmarks suffer from the same basic defect, specifically, they are based on the

returns of companies that are not even remotely comparable to that of a regulated utility.

For his large company risk premium calculation Dr. Gaske relies on the large company

stocks followed by Ibbotson' s. Ibbotson' s lists the ten largest of those companies by decile

in its 2015 SBBI Y earbook40. According to the Ibbotson' s, the largest company in decile

1 is Apple, Inc., the computer, software and cell phone giant. Aside from the fact that

Apple has a total market capitalization of $629 billion while MDU Resources, MDU

Utility' s parent company, has a total market capitalization of $4.6 billion, there is no

comparison between the lines of business of Apple and MDU, either at the parent level or

at the utility level. Further, Apple is not a rate of return regulated utility. Any attempt to

compare the required return on equity for MDU to that of Apple, or any other non­

comparable company for that matter, is fruitless in this proceeding. The Commission

should reject Dr. Gaske ' s attempt at comparing MDU to private, unregulated companies

that are in no way comparable to the regulated utility operations of MDU.

The same is true for Dr. Gaske ' s attempt to compare MDU' s utility operations to the

broader market as represented by the S&P 500. Dr. Gaske performs what he calls a

"capitalization weighted DCF calculation" based on the dividends and growth projections

of the company' s contained in the S&P 500 Stock Index4 1Again, while there may be some

utility companies represented in the S&P 500, the vast majority of the companies in the

S&P 500 are not regulated utilities, do not have business operations or services that even

remotely resemble the utility operations of MDU, and are otherwise not directly

comparable to MDU' s utility operations.

One final point regarding Dr. Gaske 's risk premium analysis. Dr. Gaske develops his risk

premium benchmarks by comparing the incremental difference in the historic returns of

stocks (large and small) over the historic returns of long term corporate bonds. While in

theory a valid risk premium can be developed based on this information, there are some

practical problems that Dr. Gaske ignores in his analysis.

First, leading authorities on cost of capital estimation, including lbbotson's and Dr. Morin,

advocate that risk premiums be based on a risk free security. The most common risk free

rates used in equity cost estimation in rate setting proceedings are those of U.S. government

bonds. These are the only securities that have no risk of default and match the investment

horizon of most utility assets. Corporate bonds, even those that are highly rated, possess

some degree of default risk.

Secondly, those same authorities advocate that the proper return to use is the income return

since this is the return that the investor expected to earn when the investment was made.

Historic corporate bond returns, such as those published by Ibbotson' s, contain not only

the income return but the appreciation of the bond as well. In order to properly develop an

accurate risk premium based on these corporate bonds the price appreciation element must

be removed from the total return. Ibbotson' s does not remove the price appreciation

element from its index of historic returns for corporate bonds and Dr. Gaske made no

attempt to do so either. Consequently, Dr. Gaske ' s risk premium benchmarks are

overstated, notwithstanding the other substantial concerns I have with his risk premium

analysis.

ARE GENERAL MARKET RETURNS OF ANY VALUE AT ALL IN

PREDICTING REQUIRED RETURNS FOR INDIVIDUAL SHARES?

As I will explain in the following section of my testimony, broader market returns are only

useful in that they give one a general sense of the appropriate range of reasonable returns

for discrete shares. Relying on such broad returns as basis for making a point estimate of

the ROE for any particular share is an exercise in futility. Even so, it is exceedingly

important to appropriately frame the range ofreasonable returns which Dr. Gaske has failed

to do in this proceeding.

WHAT IS THE RANGE OF EQUITY COST ESTIMATES INCLUDED IN YOUR

ANALYSIS?

My analysis shows that the appropriate cost of equity for MDU at this time falls somewhere

in a range of reasonableness between 6.88% and 10.59% with the mid-point of the range

being 8.24%. Of course, all of these equity cost indicators have their own individual

theoretical and practical strengths and weaknesses. History may or may not repeat itself

and can be considered only a rough guide of what may happen in the future. Likewise,

projections, particularly those made over the time horizon required by the DCF model,

while informed by various sources of data, have a speculative element to them that should

not be understated.

OCA Exhibit 201

Q. ARE THERE ANY BENCHMARKS THAT YOU CAN OFFER THE

A.

COMMISSION TO ASSIST IN NARROWING THE RANGE OF

REASONABLENESS FOR THE COST OF EQUITY IN THIS CASE?

There are a couple of benchmarks that I believe the Commission can rely upon in helping

it to narrow the range of reasonable equity cost estimates in this proceeding. Importantly,

I am not recommending that the Commission use these benchmarks in place of its own

sound decision making process or its informed judgment based on the evidence in this

proceeding. Rather, I am suggesting that these benchmarks may be useful to the

Commission in calibrating its compass with regard to the range of reasonable alternatives.

First, Ibbotson publishes two historical risk premium measures in its annual SBBI

Yearbook; the " Long-Horizon Equity Risk Premia" and the "Supply-Side Equity Risk

Premia". Ibbotson provides a thorough description of both of these risk premia which I

will only briefly summarize here. The long-horizon equity risk premium is essentially the

index that used to form the basis for my CAPM calculation discussed earlier in my

testimony expressed more generally. In this risk premium estimate Ibbotson uses average

stock market total returns over the period 1926 to 2015 and subtracts the average long-term

government bond return over that same period to arrive at an expected Equity Risk

Premium (ERP) of 6.90%. Adding to this risk premium an amount that reflects current

long-term risk free rates, in this case the current yield on 30 year U.S. Treasury Bonds of

2.452% (as of October 6, 2016), results in an estimated cost of equity capital for the overall

market of 9.352% (6.90%+2.452%=9.352%).

Ibbotson also publishes a "Supply-Side" estimate of the market equity premium. Supply­

side models are based on the theory that market returns are supplied by corporate

productivity including earnings, dividends and capital gains. Ibbotson finds that in the long

run " . . . investors should not expect a much higher or lower return than that produced by

the companies in the real economy"42. In other words, investors should expect a return that

mirrors the returns in the real economy over the long term as measured by a broad index

such as GDP. This is the same theory that underpins some of the analysis that I presented

earlier in my testimony regarding the DCF model. Ibbotson then uses this supply side

information to forecast total returns for the market over the period 1926 to 2015. Ibbotson

estimates the long-term equity risk premium for the market overall, using the supply-side

model to be 6.03% on an arithmetic basis. Combining that equity risk premium estimate

with the current long-term risk-free rate of 2.452% results in a predicted cost of equity

capital for the market overall of 8.48% (6.03%+2.452%=8.48%).

Such an Expected Risk Premium (ERP) would apply to all market equities from Toys R

Us to Boeing Aerospace. Certainly, the Commission would want to rely on a much deeper

analysis, such as the one I have done, in making a determination in this proceeding. But,

it is informative to understand that the premia data published by Ibbotson forms a range

from 8.48% to 9.352% within which an 8.9% cost of equity for MDU would be considered

reasonable. My recommended cost of equity in this proceeding is very near the mid-point

of this range while Dr. Gaske' s recommended ROE of 10.10% is well above this range.

Another source of information on the general level ERPs is published by Dr. Aswath

Damodaran who is a Professor of Finance at the Stem School of Business at New York

University. Dr. Damodaran' s work is cited extensively in the trade press. According to

data compiled by Dr. Damodaran, the implied historic market risk premium, based on

dividend yields and expected earnings growth, is 6.12% 43. These risk premiums are

estimated based upon a simple 2-stage Augmented Dividend discount model and reflect

the risk premium which would justify the current level of the index, given the dividend

yield, expected growth in earnings and the level of the long term bond rate. Dr.

Damodaran' s analysis covers the period 1960 to 2015.44

OCA Exhibit 201

Given Dr. Damordaran's implied ERP, one can derive a current equity cost estimate simply

by combining the ERP with a current measure of the risk free rate, again the yield on 30

year U.S. Treasury Bonds (as of October 6, 2016) of 2.452%. This results in an estimated

cost of equity capital for the broader market of 8.572% ( 6.12%+ 2.452%=8.572% ).

Dr. Damodaran also provides a spreadsheet model which disaggregates the cost of equity

by industry sector. The model is based on a CAPM analysis conducted by Dr. Damodaran.

Without changing any of Dr. Damodaran's input assumptions the model generates a cost

of equity for the utility sector (minus water utilities) of 5.57%. In this model run Dr.

Damodaran assumes a risk free rate of 2.27% (consistent with prevailing T-bond rates at

the time the model was updated in January of 2016) and an average utility industry beta of

.55. I reran the model with the current rate for 30 year U.S. Treasury Bonds and an average

industry beta more consistent with that published by Value Line (. 70). The resulting equity

cost estimate for the utility industry, using Dr. Damodaran's CAPM model, is 6.65%. This

is certainly lower than Dr. Damodaran's estimated ROE for the broader market and much

lower than Dr. Gaske's recommended ROE range.

While these benchmark studies are not definitive, I believe they provide a frame of

reference for the Commission in examining the recommendations made by both I and Dr.

Gaske in this proceeding. Examining the information provided by both Ibbotson and Dr.

Damodaran demonstrates that returns for U.S. equities are in the range of 8.5% to 9.3%.

Since utility equity shares are less risky than the equity market overall, we know that

returns for utility shares will be lower than the return for the market overall. In fact, Dr.

Damodaran estimates utility equity returns in the range of 6%. By way of contrast, Dr.

Gaske is recommending a range of equity returns for MDU in this case from 7.10% to

12.94%. Dr. Gaske's benchmark analysis indicates a range ofreasonable returns for MDU

that ranges from a low of 10.12% to a high of 20.00%. My research and analysis in this

case demonstrates that both Dr. Gaske's benchmarks and his recommended ROE are

excessive and should be reduced to a level more consistent with current capital market

conditions.

RECOMMENDED ROE

Q.

A.

WHAT DO YOU CONCLUDE IS A REASONABLE ESTIMATE OF THE COST

OF EQUITY CAPITAL FOR MDU?

Based on my analysis in this case, as well as the general economic and market risk

information discussed in the first portion of my testimony, together with the benchmark

information provided by Ibbotson and Dr. Damodaran, I have concluded that an 8.9% cost

of equity will balance the interests of customers in just and reasonable rates and the interest

of the utility in supporting its ability to attract and maintain capital. Although I have

calculated a number of indicators of the market cost of equity for MDU, all have their own

strengths and weaknesses. In the final analysis, I have relied more heavily on the traditional

indicators, the constant growth DCF model, the long term CAPM, and the non-constant

growth DCF model, with primary reliance on those indicators that incorporate analyst ' s

forecasts to estimate growth.

I am cognizant of the fact that popular opinion seems to support rising interest rates.

However, given that markets are very efficient, and investors are, on average, very capable

of rapidly assimilating market information, my belief is that the prospect for rising interest

rates in the future has largely already been priced into securities by investors. If investors

know, for example, that an increase in market interest rates is imminent, they would pay a

smaller price for lower returns today and forego the opportunity for greater returns when

interest rates rise. This, in tum, drives up the yield of securities in the current market.

Given my range of preferred estimates, which range from 7 .18% (CAPM) to 9 .22% (DCF),

and in consideration of my overall range which would certainly support a lower

recommended ROE, I find that an 8.9% ROE for MDU is reasonable. My recommended

ROE also falls in reasonable proximity to the range specified by both Ibbotson and Dr.

Damodaran. In contrast to my recommendation, Dr. Gaske recommends an ROE of 10.1 %

selected from his identified range that runs from 7.10% to 12.94%. Based on the evidence

that I have reviewed in my analysis, I believe that Dr. Gaske is looking in the wrong range

for a return that appropriately reflects the market and financial risks that inure to MDU's

Wyoming service territory. In my opinion, the appropriate range of reasonable equity

returns is much lower, between approximately 8.5% and 9.25%. My recommended ROE

HAVING RECOMMENDED AN APPROPRIATE ROE, WHAT IS YOUR

RECOMMENDATION AS TO THE OTHER ELEMENTS OF CAPITAL AND

6 FOR THE COMPANY'S CAPITAL STRUCTURE?

7 A. Although the cost of debt and preferred stock is discussed by both Dr. Gaske and Mr.

8 Vollmer on behalf of MDU, it is Mr. Vollmer who presents evidence in support ofMDU's

9 proposed capital structure, cost of debt, both long term and short term, and the cost of

10 preferred stock. According to Mr. Vollmer' s testimony, and Statement F attached to the

11 application, MDU is proposing a proforma cost of capital based on a test year ending

12 December 31, 2016. Accordingly, Mr. Vollmer's proposed capital ratios and costs reflect

13 those that the Company expects to be outstanding at year end 2016.

14 MDU's proposed proforma capital structure is as follows:

Long Term Debt 42.397%

Short Term Debt 5.502%

Preferred Stock 1.111%

Common Equity 50.990%

15 The actual capital structure, on an average basis, of the companies represented in my proxy

16 group is as follows:

Long Term Debt 51.23%

Preferred Stock 0.60%

Q.

A.

OCA Exhibit 201

Common Equity 48.17%

The long term and short term debt proposed by MDU, in combination, represent 47.899%

of invested capital while common equity represents 50.990% of invested capital, both

remarkably close to the median capital ratios for those capital elements in my proxy group

of companies. Since preferred equity is debt like in as much as the dividend payments on

preferred stock are contractual obligations for MDU, the preferred stock can be combined

with debt for purposes of comparison to the proxy group. Combining the debt and preferred

stock results in a debt ratio to total capitalization of 49.010%, nearly identical to that of my

proxy group. Because MDU's proposed proforma capital structure is so similar to that of

my proxy group of companies, I am recommending that the Commission adopt that

proposed capital structure for rate setting purposes in this case and I have used it in deriving

myWACC.

Regarding the cost of the vanous capital components, I have already provided my

independent analysis supporting a cost of equity of 8.9%. I have reviewed the material

provided by MDU supporting its cost of both long term and short term debt and find the

cost of each to be reasonable. The calculation of the proforma cost of long term debt of

5.363% is shown Statement F, Schedule F-1 , page 3of5 and the calculation of the cost of

short term debt of 1.828% is shown on Statement F, Schedule F-1 , page 5 of 5. Although

it is somewhat unique in my experience for a utility to break out short term debt separately

from long term debt, I do not take exception to this approach in this case.

MDU'S EMBEDDED PROFORMA COST OF DEBT APPEARS TO BE HIGHER

THAN CURRENT MARKET DEBT COSTS FOR SIMILARLY RATED

COMPANIES. WHY ARE YOU NOT RECOMMENDING AN ADJUSTMENT TO

REDUCE MDU'S DEBT COSTS?

Statement F, Schedule F-1 , page 3 of 5, shows the derivation of MDU's proposed

embedded proforma cost of debt. As can be seen on this schedule MDU has $580 million

of long term debt outstanding at the end of the proforma test year at interest rates ranging

from 3.78% to 6.33%. Importantly, MDU issued $50 million of debt in September of2016

at an anticipated rate of 4.70%. This issue will replace two $25 million outstanding issues

with rates of 6.61 % and 6.60%, respectively. This indicates to me that MDU has tracked Bryce J. Freeman 48 Docket Number 20004-117-ER-l 6

OCA Exhibit 201

the favorable interest rate environment with its most recent issuances. The 6.66% issue,

the highest rate issue outstanding before it was retired, was issued in 2009 at the height of

the financial crisis when market liquidity and credit availability was particularly low. In

his testimony Mr. Vollmer indicates that since MDU' s last rate case, it has reduced its long­

term debt cost from 6.868% to 5.363%.45

While it would be nice if the Company were able to refinance its higher cost issues and

bring its debt cost down even further, it would be inappropriate to assume, for the purpose

of setting rates in this case, that MDU has acted inappropriately by not doing so. Managing

capital contributions is much more complicated than simply issuing new debt or stock to

fund capital expansion or refinance existing capital outlays. New issues of stock and debt

have a cost associated with them, as I discussed earlier in my testimony. Additionally,

existing debt may have redemption limitations or unamortized costs associated with them.

Company' s must constantly review these factors to determine whether it is more beneficial

to refinance existing debt at a lower rate, given the costs involved, or simply continue to

pay the higher rate of the existing debt until such time as refinancing becomes economic.

This is not unlike the analysis that a homeowner would undertake when considering

whether or not to refinance a mortgage in view of the potential costs and limitations on

doing so.

There is no indication in the information provided by MDU in this proceeding that it has

acted imprudently in acquiring debt financing for its utility operations. I am confident that

MDU will continue to manage its debt cost through refinancing as those opportunities

become available in the market so as to minimize the cost of debt. For these reasons I do

not object to MDU' s proposed cost of debt and have included it in my calculation of the

W ACC in this case.

PLEASE SUMMARIZE YOUR TESTIMONY IN THIS PROCEEDING.

Certainly. My testimony in this proceeding provides an independent analysis of the current

market cost of capital that I recommend be used in setting MDU's rates for retail electric

service in the Company's Sheridan, Wyoming service territory. Mr. Anthony Ornelas of

the OCA incorporates my recommended W ACC in deriving his recommended revenue

requirement in this proceeding. Dr. Belinda Kolb provides testimony and

recommendations regarding MDU's cost of service and rate design proposals.

In my analysis I take no exception to MDU' s proposed capital structure, cost of debt or

cost of preferred stock. I am, however, recommending a return on equity of 8.9%, 120

basis points less than that recommended by Dr. Gaske on behalf of the Company. In

formulating my recommended ROE I have relied on several well vetted and widely used

equity cost estimation models incorporating multiple sources of financial and market data.

These are the standard tools and methods that I have presented to the Commission in many

previous cases. It is my belief that an 8.9% ROE will appropriately balance the interests

of customers in reasonable rates and the interests of the Company in accessing capital on

reasonable terms, as required by the Hope and Bluefield standard.

In reviewing the testimony of Dr. Gaske on behalf of the Company I have noted several

areas of disagreement between he and I, as well as mistakes made by Dr. Gaske in

formulating his ROE recommendation. It is interesting to note that if one dismisses the

floatation cost adjustment erroneously applied by Dr. Gaske in his DCF analysis, his

median DCF equity cost estimate (blended growth rate) for MDU is very similar to mine.

And, although Dr. Gaske' s presents three risk premium analyses and a market DCF

analysis in his testimony, purportedly to benchmark his 10.1 % ROE recommendation, they

are meaningless in the context of this rate proceeding. I continue to believe that Dr.

Gaske 's range of expected equity returns is unreasonable and by extension his

recommended ROE is excessive. I strongly urge the Commission to adopt my

recommended ROE of 8. 9% instead.

DOES THAT CONCLUDE YOUR TESTIMONY IN THIS PROCEEDING?

Yes, it does.
